Embodiment

The utility model is further elaborated with specific embodiment below in conjunction with the accompanying drawings.

Pressure regulator TY1, TY2, TY3 in effect major loop, transformer T1, ammeter A1, voltmeter V1 constitute the survey of estrade Try loop, i.e. major loop.TY2 coarse adjustment pressure regulator is driven by motor M1, realizes the coarse adjustment of transformer measurement voltage (or electric current). TY3 is fine tuning pressure regulator, is driven by motor M2, output is coupled to by step-down transformer T1, realize fine tuning function.Major loop Primary winding to booster (or current lifting device) produces the operating current required in transformer detection.To adapt to various boostings The change of (or up-flow) device is when loaded, it is ensured that coarse adjustment fine tuning transformer, which has to be provided with optimal adjustable range, loop, adjusts pressure regulation Device TY1, the pressure regulator needs according to circumstances to adjust in testing.In the case where key switch TY1 is connected, press button AN7 can make contactor CJ1 coil electricities and self-insurance.Test loop is connected in other contacts, and the AN8 that presses button makes CJ1 deactivation coils Electricity, so that main test loop is powered off.Coarse adjustment motor M1 controls it to rotate forward by relay J11 opened points, and it is controlled by relay J12 Reversion.Equally, J13, J14 control the rotating of fine tuning motor respectively.It is coarse adjustment motor that XK1, XK2 are switched in automatic control loop Zero-bit, limit switch XK3, XK4 of the upper limit are the limit switch of the zero-bit upper limit of fine tuning motor.J11, J12, J13, J14 distinguish For control coarse adjustment motor, the relay of fine tuning motor positive and inverse.Change-over switch K1 is mode selection switch, can be respectively placed in " manual ", " automatic ", " adjustment " 3 kinds of working conditions.Under " manual " state, AN3, AN4, AN5, AN6 button have electricity, can distinguish By manually pressing these major keys, J11, J12, J13, J14 is set to be powered and realize coarse adjustment or fine tuning motor forward or reverse.Work as electricity When machine goes to its extreme position (zero-bit or upper limit), corresponding limit switch action leads to corresponding J15, J16, J17 or J18 Electricity, and J11, J12, J13 or J14 are cut off, leave the motor off, realize position limitation protection.Under " adjustment " state, switch K1-A can connect Logical coarse adjustment motor down maneuver, K1-B connects fine tuning motor vertical motion.Until pushing down limit switch XK1 and XK4 respectively, i.e., this When state for coarse adjustment pressure regulator TY2 in zero-bit.Fine tuning pressure regulator TY3 in this case, can adjust pressure regulator TY1 in the upper limit Indicated to tester dial gauge between 9%~12%.Under " automatic " state, before AN1 startup tests are not pressed, K1-A, K1- B can connect coarse adjustment motor by relay J10A, J10B normally-closed contact respectively, and fine tuning motor declines, until two motors go to zero Position, makes relay J15, J17 act and stop, realizing self-zeroing control.AN1, AN2 are the start and stop tested automatically Key, can make relay J10A, J10B be powered and dead electricity, in the case of its energization, so as to realize a series of automatically control. J0, J1, J2, J3, J4 press point processed for the output of tester interface.J1, J2, J3, J4 action represent coarse adjustment and rise or drop, carefully respectively The instruction for increasing or dropping.As for when should which kind of action, commanded completely by tester, this Promethean function can make entirely Automatic detection process coordinating is accurate.When detection process terminates, tester J0 is acted 1 second, makes relay J10A, J10B dead electricity, And self-insurance is lost, wait presses AN1 next time, then re-starts an automatic detection process.During automatic detection, as long as pressing Pressure AN2 keys can stop detection process, and automatically control thick, fine tuning motor to zero-bit.

Described above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality With new teaching, in the case where not departing from principle of the present utility model and spirit, the change that is carried out to embodiment, repair Change, replace and modification is still fallen within protection domain of the present utility model.
